Hello Black Lighters,
I recently received (from Ebay.ca) 2 of these very nice, little, foot long 10W 365 nm
LED blacklights from China...
https://www.ebay.ca/itm/265730831488?var=565516220018
They are much cheaper ($14.85 USD/$20.10 CAD ea.) & are available in both 365 & 395 nm (nanometers). I ordered 3 more of these same 365 nm lights as well. The 365 nm
LED's are the same wavelength as the BL fluorescent tubes we have all used for years (with the regular white glass envelope that give off a pale blue light like BioQuip sold (& "Quantum" brand BL's) & are also still used in most bug zappers today). In my past experience the 395 nm (390-400 nm range) BLB lights (with the back exterior glass envelope of fluorescent tubes & the deep purple color of the new
LED's) are practically useless to attract insects. The majority of
LED lights that are sold on Ebay, Amazon, & many other places, are in the 390-400+ nm range & give off a much brighter, darker purple, visible light, made for fluorescing rocks, BL posters, paints, makeup, white clothes, glowing party decorations, etc. You may have to look around to find the 365 nm lights, but, as the one I listed above on Ebay, they can be found. Last summer, I mistakenly, in a hurry, purchased one (wrong wavelength!) of those larger 50W 395 nm
LED black lights... (square shaped &
they get extremely hot... also common on Ebay, Amazon, etc. approximately $60.00 CAD) & tried it out for a few warm, moonless, dark nights in July... very disappointed as next to nothing flew to that light. I also, recently this winter, purchased yet another 50W
LED BL (but...365 nm this time!); can't test any of the new lights yet as there is still snow on the ground in many places here & freezing temps. at night. Certainly one can use some of these much more expensive combo 365/395 nm
LED BL's (can't hurt I (would think?), but I, IMHO, have little faith in the effectiveness of the strictly 390-400 nm wavelength
LED's. In summary I will be experimenting with all my new
LED 365 nm black lights in the coming months & can report back later. Please note that these are my own personal recommendations/suggestions & are based solely on my own past experiences & your future results may differ widely...
